Preparation of microcrystalline cellulose from Rabdosia rubescens residue and study on its membrane properties

Abstract Microcrystalline cellulose (MCC) was prepared easily from Rabdosia rubescens residue to realize the efficient utilization of waste resources. The yield was about 95.03% under the optimal conditions. Then, MCC membrane was prepared by phase transformation method and its structure and mechani...
